Job Description

We are making travel effortless. Join us.
Whether it’s to visit the people closest to us, starting an exciting adventure, or a career-defining business trip, travel is an essential part of our lives. Yet we've all experienced the aches and pains of getting to our destination. Today, more than 4 billion airline passengers rely on technology that hasn't kept up with the expectations of the modern connected traveller.
That’s why we’ve started to rebuild the infrastructure that underpins the travel industry. We’re on a mission to unravel travel — simplifying systems and building the tools that will make the future of travel effortless.
We were part of Y Combinator S18's cohort and we are backed by Benchmark, Blossom, Index Ventures and Kima Ventures. A fantastic set of investors that has helped build some of the world's largest companies.
Something to consider when reading this job advert
We know people engage with job adverts differently. Some will view it as a checklist that needs to be at 100% before applying; others will see 60% as good enough. If you think you have what it takes but don't necessarily meet all the requirements on the job description, please still get in touch. We'd love to have a chat, learn more about you and see if it could be a great fit.
Site Reliability Engineering at Duffel
As an SRE at Duffel, you’ll be part of a small team within engineering that is responsible for the Software Development Life Cycle, and setting the golden standard for developing and running applications within the Duffel technology stack. You will be working closely with engineering teams to understand their needs and help meet the demands of our product as we scale globally.

What we're looking for in you

  • An enthusiasm for software development and systems engineering.
  • An interest in working with Go, this is what we mostly work with. Previous experience isn't necessary and learning on the job is absolutely fine. What's more important is your general engineering ability rather than your knowledge of a particular language or framework.
  • A high bar in code quality, infrastructure and database design.
  • Good understanding of operational and observability practices.
  • Big picture thinking - you can make trade offs on technical work streams against business impact.
  • Fantastic communication skills. You're able to articulate what you're working on and why to the team in a clear and structured way.
  • You thrive in a collaborative environment. You believe in your own methods but keep an open mind, taking suggestions and feedback onboard as well.
  • Be part of a paid on-call rota responsibilities with a focus on postmortem writing, reviewing and resolution for long-term health of our systems.

Technologies

  • You’ll be mostly building software using Go.
  • We run on Google Cloud platform, so you’ll be helping to run a few of their products such as BigQuery, Pub/Sub, CloudSQL and more.
  • We manage our infrastructure as code resources via Terraform.
  • We follow a Gitops approach to managing our Kubernetes configuration, using ArgoCD and Helm.
  • We manage a high-availability metrics collection system using Grafana, Thanos & Prometheus.

What you'll be working on

  • You’ll be part of a team iterating on our internal product, a Go-based command-line tool we’ve created for engineers across Duffel to manage deployment and configuration of their applications, as well as improving the interface between engineers and the underlying platform we maintain.
  • Maintain our Continuous Integration and Continuous Delivery experience.
  • Provide better metrics retention and availability.
  • Upgrade our PostgreSQL databases to the latest version with minimal, and preferably zero, downtime.
  • Help maintain and deliver our data pipelines in Google Cloud Platform.
  • Provide in-depth reliability expertise and operational excellence on a daily basis to the rest of our software engineers.
  • Build and maintain tooling to enable us to better manage our infrastructure, and provide a great developer experience for our internal users.

What you can expect from us
We’re dedicated to your personal growth. Our environment is comfortable physically, but also in that our ears are always open to any ideas, concerns and questions. We believe that everyone should have pride in their work, taking full ownership of it and its impact. That’s why everyone who joins Duffel owns a share of the company.
We are an equal opportunities employer. We believe that the key to our success is employing a diverse team, that’s why recruitment decisions are only based on your experience and skills.

The FlexScore® is the result of a rigorous 2-step verification of a company’s flexibility

First we assess the flexibility options Duffel provides and then we anonymously survey a statistically significant proportion of their employees to make sure Duffel is as flexible as they say they are. Our assessment is based on the six key elements of flexibility: location, hours, autonomy, benefits, role modelling and work-life balance.

We ask the hard questions so you don’t have to.
